Some rare atoms can store quantum information, an important phenomenon for scientists in their ongoing quest for a quantum Internet. New research exploits a system that has the potential to transfer optical quantum information to locally stored solid-state quantum format, needed for quantum communication.
“Our research aims at creating a quantum analog of current fiber optic technology in which light is used to transfer classical information — bits with values zero or one — between computers,” said author Dirk Bouwmeester, a professor in UCSB’s Department of Physics. “The rare earth atoms we’re studying can store the superpositions of 0 and 1 used in quantum computation. In addition, the light by which we communicate with these atoms can also store quantum information.”
